DBWS DDLParser: Parser returning type name with prepended schema name
for types that are columns in a table

Change columnSpec() in DDLParser.jjt to check for dotted-name
for column type; if the first part of the dotted-name is the same
as the enclosedType's schema name, only use the second part as
the name of the column type
